Substitute Part Grouping Explanation

Substitution of the T520B227M2R5ASE070 is determined by strict equivalence across the following critical parameters:

  • Capacitance Value: 220 µF (exact match required)
  • Voltage Rating: 2.5 V (exact match required)
  • Package / Case: 1411 (3528 Metric) (exact match required)
  • ESR Specification: 70 mOhm @ 100 kHz (exact match required)
  • Mounting Type: Surface Mount (exact match required)
  • Operating Temperature Range: -55°C to 105°C (exact match required)
  • Tolerance: ±20% (exact match required)

The T520B227M2R5ATE070 qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction between these parts is packaging format and product status.

Engineering Selection Recommendations

The T520B227M2R5ATE070 is the direct substitute for the obsolete T520B227M2R5ASE070. Both parts share identical electrical performance and mechanical specifications across all critical parameters.

Product Status Consideration: The T520B227M2R5ASE070 is classified as obsolete, while the T520B227M2R5ATE070 maintains active product status. This distinction ensures long-term supply availability and continued manufacturer support for the substitute part.

Compliance Consideration: The T520B227M2R5ATE070 is ROHS3 compliant, whereas the main part is RoHS non-compliant. Applications subject to RoHS regulatory requirements benefit from substitution to the compliant variant.

Packaging Consideration: The main part is supplied in tube packaging, while the substitute is supplied in Tape & Reel (TR) format. This difference affects handling, storage, and automated assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the T520B227M2R5ATE070 be used as a direct replacement for the T520B227M2R5ASE070?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including capacitance (220 µF), voltage rating (2.5 V), ESR (70 mOhm @ 100 kHz), package type (1411 / 3528 Metric), and operating temperature range (-55°C to 105°C).

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. The T520B227M2R5ASE070 is obsolete and supplied in tube packaging. The T520B227M2R5ATE070 is active and supplied in Tape & Reel format. Additionally, the substitute part is ROHS3 compliant.

Q: Are there any PCB layout or assembly considerations when switching to the substitute part?

A: No. Both parts share identical physical dimensions (0.138" L x 0.110" W, 3.50mm x 2.80mm) and maximum seated height (0.079" / 2.00mm). PCB footprints and assembly processes remain unchanged.

Q: Does the Tape & Reel packaging affect component performance?

A: No. Packaging format does not affect electrical or mechanical performance. The difference is in handling and automated assembly compatibility.

Q: Is the substitute part suitable for RoHS-regulated applications?

A: Yes. The T520B227M2R5ATE070 is ROHS3 compliant, making it suitable for applications subject to RoHS directives. The original part is RoHS non-compliant.
